Abstract
A tapping screw (1) having a screw shaft (3) and a drill portion (4,5) stepped into two or more sub-portions having different diameters gradually reducing toward the tip of the screw. The small-diameter drill portion (5) has a larger drill angle than the large-diameter drill portion (4). The former firstly forms a starting hole and the latter expands it. Thus a less force is required to turn the screw than a conventional tapping screw. <IMAGE>
